Description
Technical field
The present invention relates to lead-acid accumulators to repair field, more particularly to a kind of lead-acid battery repair agent and lead acid storage battery
The restorative procedure in pond.
Background technique
Lead-acid accumulator is a kind of chemical energy source being widely used in the fields such as communication, electric power, railway, traffic, and China is
Produce and use in the world the big country of lead-acid accumulator.The various batteries that China is scrapped every year reach several hundred million, and every year all
Increasing.It is a global problem that battery, which scraps processing, arbitrarily abandons, would seriously pollute the environment, directly endanger the mankind
Itself.
Therefore, the reparation of lead-acid accumulator is worldwide popular research topic.The service life of lead-acid accumulator
Mainly determined by the accumulating rate of the corrosion-deformation speed of anode plate grid and irreversible sulfation.In general, grid is rotten
Erosion is longer to the period finally scrapped, and irreversible sulfation is to influence the main and most common original of the life of storage battery
Cause.
The lead-acid accumulator of normal use forms lead sulfate crystallization in electric discharge, can relatively easily restore in charging
For lead.If the operation and maintenance of battery is not good at, such as lays up or often undercharge, overdischarge etc. for a long time, cathode
On will gradually form a kind of coarse hard lead sulfate crystallization.This lead sulfate crystallization is non-conductive, in conventional charging modes
Under be difficult to decompose, this phenomenon be referred to as " irreversible sulfation ", it plugs pore and the outer surface of pole plate, hinders
Electrolyte reacts with active material, reduces the actuating quantity of active material, so as to cause the internal resistance increase of battery, capacity
Decline, eventually leads to scrapping for lead-acid accumulator.The main reason for irreversible sulfation " formation is that the recrystallization of lead sulfate is existing
As solubility reduces and then can not be decomposed after causing coarse crystallization to be formed.
The method repaired at present to lead-acid accumulator specifically includes that hydrotherapy reparation, large current charge reparation, high frequency arteries and veins
Punching is repaired, chemical activating agent reparation etc..These methods repair major defect existing for lead-acid accumulator battery include: may only portion
Sulfation problem of determining is decomposed, and may be decreased the amount of inside battery active material and/or damaged inside battery structure,
Lead-acid accumulator after reparation occurs capacity quickly and declines and be quickly invalidated, and battery life is short after reparation, such as only 4-5
Month；Structural stability is poor, is easily damaged；Over-discharge property is poor, such as cannot provide matched electric energy in electric car acceleration and deceleration.
Summary of the invention
The purpose of the invention is to overcome the deficiencies of existing technologies, the renovation agent and plumbic acid of a kind of lead-acid accumulator are provided
The restorative procedure of battery.

Agent includes: sodium sulphate, ammonium sulfate, manganese dioxide, sodium hypophosphite, trifluoroacetic acid, ammonium phosphate and pyrogallol.
In addition, the present invention also provides a kind of restorative procedures of lead-acid accumulator, which is characterized in that this method comprises:
Step 1: detection battery capacity: lead-acid accumulator to be repaired being put on capacity detector and is detected, and is discharged
End when to 10.5 volts, selects discharge time in 30 minutes or more lead-acid accumulators；
Step 2: addition renovation agent and deep discharge: the lid for the lead-acid accumulator that opening steps one select optionally supplements
Electrolyte supplements any one of a certain proportion of claim 1-6 institute according to the nominal capacity of lead-acid accumulator to be repaired
The renovation agent stated；Then lead-acid accumulator is put into discharge instrument, deep discharge is carried out to zero volt to battery；If necessary to supplement
Electrolyte, it is preferable that addition electrolyte temperature control is at 20-30 degrees Celsius；Preferably, the electrolyte includes ethylene carbonate
